The machine is a fully electronic single thread chainstitch machine capable of sewing both single and double row tack. The chainstitch special application machine S-4000 TFK Label leader ensures automatic feeding of labels from a roll, folded, unfolded or turned and loaded from the top. The chainstitch tack provides increased productivity over the lockstitch competition as bobbin changes are eliminated. This chainstitch special application machine S-4000 TFK Label leader is far superior for elastic fabrics such as knitwear because of the stitch flexibility.

The electronic start and stop motion extends machine life and improves machine reliability by eliminating the stop motion and clutch mechanisms.
The S-4000 contains six patented mechanisms:
DC Drive Motor is fully enclosed within the head casting, eliminating the need for an under the table mounted clutch motor, pulley, belt and brake. This reduces required maintenance and eliminates oil and dust around the working area.
The microprocessor control ensures maximized ramp-up and ramp-down speeds to achieve minimized cycle times.
Chainstitch buttonholing provides increased productivity with no bobbin change. The elasticity of the chainstitch also provides the flexibility needed for many fabrics such as knitwear.
The S-4000 series is equipped with the drip oil wick lubrication system and oil level monitor. This system prolongs the machine life and reliability.
The S-4000 series has electronically adjustable sewing speed up to 3,800 spm and are the fastest chainstitch buttonhole and special application machines available. Due to the DC Drive Motor the machine is 20% faster than other models. The noise level is also significantly lower on the S-4000.
